First 32bit Arduino-Compatible available from Digilent

chipKIT Uno32™ Arduino™-Compatible Prototyping Platform combines compatibility with the popular Arduino™ open source hardware prototyping platform with the performance of the Microchip PIC32 microcontroller. The Uno32 is the same form factor as the Arduino™ Uno board and is compatible with Arduino™ shields. It features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply.
The Uno32 board takes advantage of the powerful PIC32MX320F128 microcontroller. This microcontroller features a 32-bit MIPS processor core running at 80Mhz, 128K of flash program memory and 16K of SRAM data memory.
The Uno32 can be programmed using an environment based on the original Arduino™ IDE modified to support PIC32. In addition, the Uno32 is fully compatible with the advanced Microchip MPLAB development environment and the PICKit3 in-system programmer/debugger.

The chipKIT™ Max32™ combines compatibility with the popular Arduino™ open source hardware prototyping platform with the performance of the Microchip PIC32 microcontroller. The Max32 is the same form factor as the Arduino Mega board and is compatible with standard Arduino™ shields as well as larger shields for use with the Mega boards. It features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply.
The Max32 board takes advantage of the powerful PIC32MX795F512 microcontroller. This microcontroller features a 32-bit MIPS processor core running at 80Mhz, 512K of flash program memory and 128K of SRAM data memory. In addition, the processor provides a USB 2 OTG controller, 10/100 Ethernet MAC and dual CAN controllers that can be accessed via add-on I/O shields.
The Max32 can be programmed using an environment based on the original Arduino™ IDE modified to support PIC32. In addition, the Max32 is fully compatible with the advanced Microchip MPLAB development environment and the PICKit3 in-system programmer/debugger.

About Arsenio Spadoni

It is not “First 32bit Arduino-Compatible”. It may be the “First 32bit Arduino-Compatible available from Digilent”, but I think that is extremely misleading.

If one makes the effort to check the “First …” claim, at say Wikipedia:http://en.wikipedia.org/wiki/Arduino
There are a bunch of 32-bit Arduino compatibles. I have owned a LeafLabs Maple, for about a year. It implements the Arduino libraries on a fork of the Arduino IDE, uses the same gcc under the covers. I think LeafLabs Maple was available in 2009, but you’d have to do some checking to confirm that.

Like most 32-bit processors, it runs at 3.3V, and not 5V like an Arduino.
Not at all surprisingly, some functionality on pins is different to an Arduino. I have no problem with that. I wouldn’t want them to spend a pile of cash trying to exactly replicate an ATmega.

The analysis at ruggedcircuits.com also notes that some of the Arduino language hasn’t been ported, but that is just software, so I’d expect that to get done at some stage.

Please remove the “First” from the title, and note that it isn’t fully hardware compatible, and the article is fine.

I am not a member of LeafLabs staff, and have no financial interest in LeafLabs.

Nothing is 100% compatible, especially if you replace an 8-bit core with a 32-bit core from another brand. But in this case, with a very little job you can use virtually all the Arduino’s libraries to get more powerful devices. This means the phrase “First 32bit Arduino-Compatible”
We know very well LeafLabs Maple, but that’s another thing.
Note that – like you – we have no interest in Microchip, Digilent or Arduino.
